Silicone adhesive is divided into silicone resin based adhesive and room temperature vulcanized silicone rubber based adhesive, the former is mainly used for bonding metal and heat-resistant non-metallic materials, the adhesive can be used in the temperature range of -60-120℃; The latter is mainly used for bonding heat resistant rubber, bonding rubber and metal and other non-metallic materials.
Silicone resin is silicon - oxygen - silicon as the main chain, silicon atoms on the connection of organic groups of cross-linked semi-inorganic polymer, it is made of multi-functional silicone by hydrolysis condensation, under the action of heating or catalyst can be further transformed into a three-dimensional structure of insoluble unfused thermosetting resin. Silicone resin can be divided into methyl silicone resin, phenyl silicone resin, methyl phenyl silicone resin according to the different connecting groups on the silicon atom.
